Abstract: A radar system with a phase controlled antenna array that contains a number of data and supply networks (2), which are installed so that they are interchangeable, and a transmit/receive module (3) containing a transmitter and receiver circuit (4) as well as a number of circulator circuits (8) and a number of antenna elements (9) that are coupled via a circulator circuit (8) to the transmitter and receiver circuit (4). Transmitter and receiver circuits (4), circulator circuits (8), and antenna elements (9) are combined in each transmit/receive module (3) and the transmit/receive modules (3) are arranged interchangeably on the radiation side of the radar or EW system (1).
